I have been testing some video creation software to make photo presentations: MS Photo Story,  MemoriesOnTV and Wondershare's Movie Story.  The latter only allows saving MPEG in the Home version that I am trying (pro allows AVI) and it gives me a choice of NTSC or PAL, whereas Photo Story saves only in WMV and it gives me choices of sizes and fps based on the desired use (computer, video, PDA).  Movie Story has many file type options and settings, although the presentation tools lack a bit.

What format - WMV, AVI, MPG - gives the best quality?  I know I must save at the highest fps, which is normally 30.

avi.
Since this is a container format, you can use a codec you want, mainly the quality of the video depends on the codec, not on the format. Some codecs work better and produce less file size. I recommend to use divx or ffdshow in avi, 1-pass quality based, here you will control the qualit/compression as in jpeg.

I don't think I have those options even in Movie Story (the only encoder it uses for AVI is XviD).

I don't get much information about the files in Windows file properties.  I opened several files in MovieMaker, as it allows me to get more info about the files.

WMV videos created with Photo Story have a bitrate of around 100kbps at 30fps.  MPG videos created with MOTV show bitrates of around 160000kbps at 30fps - is that high bitrate true?  The only video I created with Movie Story shows 30fps, but no bitrate appears in properties.

Some high quality videos I created in Movie Maker have a bitrate of 1900kbps and 25fps.  In fact, all files generated with MM are 25fps.

I'm surprised that none of the old fashion film videographers have not came in mass to protest, by saying PAL give smoother and more arty results... You are right 30 is best, 60 is better, 120 is awsome  :)

Vonkara,

As you may have noticed, I don't know much about videos and I feel confused about all those numbers.  I believe that 30 is better than 25, as it would mean a smoother transition.  Isn't it so?

Simply explained, 25fps blur the action in a video more quickly. I don't know the exact term in english though. I'm not a pro either. Still... remember the old webcams as a extreme example. All was blurry the second something was moving in the images. Those cam was like 15fps though.

But I always liked NTSC more for it's crisper images when the action go on. Nikon does all their video/photo cameras at 25 fps grrr...

Maybe 25 or 30 don't matter much?  As I said, videos from Movie Maker are at 25fps and I think they look excellent.  Maybe other parameters are more important than this difference in fps?

It is difficult to compare the videos, as I have to watch them separately, but the MPG has some sort of "flicker", if I may call it that way, as an image is zoomed in, that the WMV file doesn't show.

Yea, it matter only if the subjects move quickly in the frame or if the camera shake a lot actually. You can see the difference if you do slow motion or image per image playing though.
